Description

Technical Field

[0001] The invention relates to the technical field of seed air drying, in particular to a hot air box and a seed air drying system. Background Art

[0002] By reducing the moisture content of seeds, the respiration of seeds can be slowed down, thus extending their vitality during storage. Dry seeds are not conducive to the growth of mold and pests, reducing the risk of mildew and pests during storage. Proper drying can ensure that seeds have a good germination rate and growth potential when sown.

[0003] The most common method for seed drying is to use conventional grain drying methods (hot air drying), such as adding air to the drying box, and stirring or vibrating the seeds to achieve uniform drying. However, for seeds that need to be used for breeding, while stirring or vibrating to achieve a uniform drying effect, stirring or vibrating will cause varying degrees of damage to the seeds, resulting in a low seed drying yield, which affects subsequent breeding results. The solution to the above problem is air-blowing static drying equipment. In the scenario of large-scale seed drying, air-blowing static drying equipment needs to control multiple drying equipment separately, and there is a problem that the seed drying time cannot be accurately controlled, resulting in the seed drying yield cannot be guaranteed. Summary of the invention

[0004] Some simplifications or omissions may be made in this section and the abstract and title of the present application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0005] In view of the above-mentioned prior art problems, the present invention is proposed.

[0006] The invention aims to provide a hot air box, which aims to solve the problem of low seed drying yield.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a hot air box, comprising a drying box, a first hot air outlet connected to the interior of the drying box, and a sensor arranged inside the drying box, wherein the sensor is used to measure the temperature and humidity of each part;

[0008] A filter screen is arranged inside the drying box.

[0010] As a preferred embodiment of the hot air box of the present invention, the drying box comprises a first surface and a second surface, and there are three channels between the drying box and the first hot air outlet, one of which is located between the filter and the first surface; and valves are provided in the three channels.

[0011] As a preferred solution of the hot air box of the present invention, wherein: the channels are all connected with air outlet pipes, and the air outlet pipes extend to the interior of the drying box.

[0012] As a preferred solution of the hot air box of the present invention, at least one air outlet pipe is provided corresponding to the channel.

[0013] As a preferred solution of the hot air box of the present invention, the air outlet pipe is a non-linear pipe.

[0014] As a preferred solution of the hot air box of the present invention, an air outlet is provided on the side of the drying box.

[0015] The beneficial effects of the hot air box of the present invention are as follows: the present invention can accurately judge the degree of seed drying through the cooperation of temperature and humidity sensors and microprocessors. When multiple sensors in the same box reach the threshold at the same time, the corresponding electronically controlled valves are automatically closed to avoid over-drying or under-drying of the seeds, thereby effectively ensuring the drying yield of the seeds.

[0019] As a preferred solution of the seed air-drying system of the present invention, a valve is provided inside the branch air duct.

[0020] The seed air-drying system of the present invention has the following beneficial effects: multiple drying boxes can be controlled to work simultaneously without affecting each other, so that one hot air tower can supply heat and multiple drying boxes can work synchronously, thus greatly improving the drying efficiency.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figure 1, which is the first embodiment of the present invention, and provides a hot air box, comprising a drying box 100, a first hot air outlet 101 communicating with the interior of the drying box 100, and a sensor 102 disposed inside the drying box 100, wherein the sensor 102 is used to measure the temperature and humidity of each part;

[0034] The filter 103 is arranged inside the drying box 100 .

[0035] Among them, the filter 103 is attached to the inner wall of the drying box 100, wherein the first hot air outlet 101 is connected to the inside of the drying box 100, and the connecting port is between the filter 103 and the bottom of the drying box 100. The advantage of this design is that the seeds to be dried are placed above the filter 103 to prevent the seeds from slipping and blocking the hot air outlet. Secondly, this design can also utilize the upward movement property of hot air to dry the seeds from bottom to top.

[0036] At the same time, sensors 102 are set at different positions of the drying box 100. This design can detect the temperature and humidity of multiple positions of the drying box 100. The hot air moves upward from the bottom and then takes away the moisture. At the same time, the sensors 102 at different positions can detect the position temperature and humidity of each area inside the drying box 100. When the temperature and humidity of all sensors 102 meet the standards, the internal seeds are all dried. At this time, the first hot air outlet 101 can be directly closed. This first hot air outlet 101 is connected to a hot air blower to provide hot air for seed drying.

[0037] In summary, the seeds are placed inside the drying box 100, the filter 103 holds up the seeds, and then the first hot air outlet 101 is used to deliver hot air to the drying box 100. The hot air is delivered from below the filter 103 to the bottom of the drying box 100, and the hot air begins to rise; when the temperature and humidity of the sensor 102 meet the standards, the hot air delivery from the first hot air outlet 101 is stopped.

[0038] Example 2

[0039] Reference Figures 1 to 5 , which is the second embodiment of the present invention, includes a sensor 102 including a first temperature and humidity sensor 102a, a second temperature and humidity sensor 102b, and a third temperature and humidity sensor 102c, and the first temperature and humidity sensor 102a is located at the bottom of the drying box 100, and the third temperature and humidity sensor 102c is located at the top inside the drying box 100.

[0040] Among them, the sensor 102 extends from the level of the filter 103 to the level of the top of the drying box 100, wherein the sensor 102 is evenly distributed with three temperature and humidity sensors, namely, a first temperature and humidity sensor 102a, a second temperature and humidity sensor 102b, and a third temperature and humidity sensor 102c; wherein the temperature and humidity sensors are all commercially available equipment for collecting temperature and humidity; the sensors 102 are respectively placed at the four corners and the center of the drying box 100, and such a design is equivalent to placing temperature and humidity sensors at the four corners and the center of the drying box 100, which is equivalent to placing five first temperature and humidity sensors 102a at the level of the filter 103, five second temperature and humidity sensors 102b at the level between the filter 103 and the top of the drying box 100, and five third temperature and humidity sensors 102c at the top of the drying box 100. The advantage of such a design is that the drying box 100 is divided into three layers, and the temperature and humidity of seeds in different layers are monitored, so that the degree of seed drying inside the drying box 100 can be monitored.

[0041] The drying box 100 comprises a first surface 100a and a second surface 100b. There are three channels between the drying box 100 and the first hot air outlet 101, one of which is located between the filter screen 103 and the first surface 100a; and valves are provided in the three channels.

[0042] Among them, the inner bottom surface of the drying box 100 is the first surface 100a, and the inner upper surface of the drying box 100 is the second surface 100b. At the same time, a channel with a valve is arranged between each layer of temperature and humidity sensors; a channel is arranged between the filter 103 and the bottom of the drying box 100, a channel is arranged between the first temperature and humidity sensor 102a and the second temperature and humidity sensor 102b, and a channel is arranged between the second temperature and humidity sensor 102b and the third temperature and humidity sensor 102c, and a switchable valve is arranged between each channel. This design can switch the corresponding valve according to the regional temperature and humidity detected by the internal temperature and humidity sensor, adjust the corresponding regional hot air delivery amount, and reduce the damage rate of the seed drying process.

[0043] The channels are all connected with an air outlet pipe 104 , and the air outlet pipe 104 extends to the interior of the drying box 100 .

[0044] Among them, each channel is connected to an air outlet duct 104 at the internal opening of the drying box 100, and the air outlet duct 104 is a sleeve structure with one end closed, and the open end is connected to the channel; the outer wall of the air outlet duct 104 is evenly arranged with through holes, and the through holes connect the inside of the air outlet duct 104 with the outside. When hot air is input from the first hot air outlet 101, it then enters the air outlet duct 104 through the channel, and then is discharged from the air outlet duct 104 through the through holes and enters the interior of the drying box 100. The advantage of such a design is that it can allow the hot air to be blown more evenly from the channel to the side of the drying box 100 away from the channel.

[0045] At least one air outlet pipe 104 is provided corresponding to the channel.

[0046] It should be noted here that the open end of the air outlet pipe 104 is inserted into the interior of the channel, at which time the channel can be blocked, and then different air outlet pipes 104 are controlled by individual valves; multiple air outlet pipes 104 are arranged in an array along the bottom plane direction of the drying box 100 at the same channel. The advantage of this design is that the hot air can be spread out horizontally and move upward to make the hot air distribution more even, and cooperate with the sensors 102 at the four corners and the center position to better monitor the hot air volume inside the drying box 100. According to the temperature and humidity conditions at different positions, the valves corresponding to different air outlet pipes 104 can be adjusted to reduce the air volume at the corresponding position to prevent the temperature from being too high, which will cause the seeds to be over-dried and damage the finished product.

[0047] The air outlet pipe 104 is a non-linear pipe.

[0048] like Figure 5 As shown, the air outlet pipe 104 is divided into multiple areas, and the width between each area is the same. The advantage of this design is that when one end of the port is closed, the internal air volume will reach saturation, and the air volume at each position of the air outlet pipe 104 will be roughly the same, ensuring that the air volume in a plane is uniform, and trying to ensure that the seeds receive uniform air volume.

[0049] An air outlet 106 is provided on the side of the drying box 100 .

[0050] The air outlet 106 is the exhaust port of the drying box 100. At the same time, the air outlet 106 is arranged on the side, that is, other surfaces other than the first surface 100a and the second surface 100b, and the air outlet 106 is located in the middle of the first surface 100a and the second surface 100b. The advantage of this design is that the drying box 100 has three layers of air outlet ducts 104 built in, and the air outlet ducts 104 in the middle layer and the upper and lower air outlet ducts 104 will form airflow collisions, but because the air outlet 106 is in the middle position, the gas will escape toward the air outlet 106; the advantage of this design is that when in use, the middle layer can be controlled by the valve first. The air volume of the air outlet duct 104 is larger, and the air volume in the middle position is larger, so that the hedging position is closer to the upper and lower surfaces of the drying box 100. When the second temperature and humidity sensor 102b detects that the seeds in the middle layer are basically qualified for air drying, the air volume of the air outlet duct 104 in the middle layer can be closed or reduced, and the air volume of the upper and lower air outlet ducts 104 can be increased. Since the air outlet 106 is in the middle position, the hedging wind will escape to the air outlet 106. At this time, as long as the temperature and humidity sensor indicators inside the drying box 100 meet the standards, the air drying is completed. This solution greatly reduces the problem of insufficient yield caused by the traditional drying box 100.

[0051] Example 3

[0052] Reference Figures 1 to 7 , which is the third embodiment of the present invention, further provides a seed air-drying system, including a hot air tower 200 connected to the first hot air outlet 101 through a main air duct 201 .

[0053] The hot air box is connected to the main air duct 201 through a branch pipe 202 , and the branch pipe 202 is connected to the first hot air outlet 101 .

[0054] A valve is provided inside the branch air duct 202 .

[0055] like Figure 6 As shown, the top of the hot air tower 200 is connected to the main air duct 201, the main air duct 201 is connected to the first hot air outlet 101, and the hot air outlet 101 is connected to the channel through the branch air duct 202. At the same time, each branch air duct 202 controls the air volume of a drying box 100, and a controllable valve is set inside each branch air duct 202. The advantage of this design is that the air volume switch of each drying box 100 can be controlled to achieve simultaneous air drying of multiple drying boxes 100 without affecting each other.

[0056] At the same time, the air duct is set as a circular overhead pipe close to the factory wall, making full use of the factory space, and the air duct is covered with thermal insulation materials such as rock wool and polyurethane foam, which reduces the heat loss of hot air during the transportation process and improves energy utilization efficiency, achieving the effect of saving space and reducing heat loss.
